no other program is already running on the port used by Gnomemeeting.

Comment 1 Daniel Reed 2004-09-08 14:31:27 EDT
Open a terminal and examine the output of (run as root):

netstat -l -v -p -n

This should show which process is listening on port 1720 (which is
what gnomemeeting wants). If it is another instance of gnomemeeting,
see if you can find where it is and either use that instance or kill
it. If it is something else, you may need to shut it down. If it is
something else and you think gnomemeeting and the other process
shouldn't conflict with each other, feel free to reopen this and
include the output of the netstat command (above).

Comment 2 kaye gee 2004-09-08 17:39:59 EDT
The output from the command showed that port 1720 was not used by
anything. I'm not sure what caused this, but I rebooted the box and it
cleared the port. Was it a bug??? If it was, it would probably be hard
to track down the root cause.

tcp        0      0 :::1720                     :::*                 
      LISTEN      -
